About this unit
Persian has several letters for the same sound. These four come mostly from Arabic words.
- ثs, the same sound as سثَبات · stability
- ص
s, the same sound as سصَندَلی · chair - ح
h, the same sound as هحوله · towel - ذz, the same sound as زآذَر · Azar, an Iranian month
One letter, several shapes
A letter's shape depends on its neighbours. At the start it joins only the next letter, in the middle both neighbours, at the end only the letter before it.
A dash means the letter never joins the next letter: at the start of a word it looks as when alone, in the middle as at the end.
| Sound | Letters |
|---|---|
| s | س · ص · ث |
| h | ه · ح |
| z | ز · ذ |
Your ear cannot choose between them: learn the spelling with the word.
